Since this talks about sleep quality I want to add something that was almost unknown to me for over 30 years. Smartwatches AFAIK don't have CO2 sensors. It seems to me though, that that would be extremely useful for sleep quality tracking. I have just a couple of years ago found out that CO2 levels are having the highest impact on my sleep quality besides temperature. I can highly recommend getting a CO2 sensor to get a good feeling for that effect. Also understand how much air is available in your room and how much CO2 your body produces per hour. I totally underestimated this until I was able to measure it. In a small sleeping room with closed doors the amount of CO2 will reach unhealthy levels at the end of the night.

Re: Training my smartwatch to track intelligence
#62I work in neurotech/sleeptech and though I commend @dmvaldman on the project, it falls for some of the common flaws of current sleep medicine/research and some strange decisions in the program itself.
Measuring sleep by time is an antiquated idea, and the industry is just barely starting to move away from this metric. You wouldn't measure your diet based on how much time you spend chewing.
Decreased slow-wave activity, the hallmark of deep sleep, can increase time spent in deep sleep as your brain tries to compensate for the lack. This only works to a certain point, and with significant decrease, such as after drinking alcohol, your brain is unable to make up for the deficit and is actually unable to stay in deep sleep. The deep sleep length doesn't map directly to function.
Chess is an interesting metric because there is an opponent being played against, so what does that really say about the players mental clarity? There are too many factors.
I wonder if sleep regularity (consistent wake in particular) was a metric which was fed into the algorithm, and if it did not correlate?
Though many people say "garmin (smartwatch X) isn't good at tracking" that misses the point that tracking time isn't a valuable metric, and why so many people say "my sleep score doesn't match what my watch tells me".
Beyond just tracking, we have the ability to directly enhance the Neural Function of Sleep, and this is what we're working on at https://affectablesleep.com
However breaking people away from the "sleep time metric" is a challenging one.

I’m surprised people need this data. Are they not aware if they had a good night sleep? Always had been obvious to me.
I think it’s more a way to explore the effects certain other behaviours can have on your sleep quality; for instance does a magnesium supplement help you get more deep sleep, what about workout timing does it effect how long it takes to fall asleep or interruptions and so on. I don’t trust the raw numbers at all, really, but since i’m wearing the same sensor i can use it to spot trends at least. Or that’s what i tell…
How did you know it was magnesium supplement? There is no control and n=1.

#64Has anyone looked into creatine? I've seen more mentions of creatine supplementation for cognition performance.
see https://fitnessvolt.com/rhonda-patrick-and-darren-candow-cre... and https://www.foundmyfitness.com/topics/creatine
Not much research in this area and I don't see anyway that a smartwatch can/could track this.

I'll also add in getting a standalone sensor (I went with Aranet) gave me insights into this was well, as a non smart watch wearer

> I've slept with my watch for a while (stopped because the battery is crap and I need to charge it every day or it won't last past noon the next day) and I've had the same adjustment period. I'm guessing this is an Apple Watch? Garmins typically last a week or more.
I wear Huawei WatchFit during sleep, battery also lasts over a week. I didn't know Apple Watch batteries are that bad.
I dare you to sniff it

#67> Often, it would also contradict how I was internally feeling. I’d wake up feeling rested, see my stats are low, and play a game of chess out of algorithmic rebellion, only to feel my mind up against a barrier and handedly lose. It would be better to only look at the stats after playing if you want to verify it, this could easily be a self-fulfilling prophecy.
My thoughts exactly! The barrier could be mental, induced _by_ the app

Re: Training my smartwatch to track intelligence
#69The biggest thing for me is I don't understand how people can sleep with these watches on, it's so uncomfortable to me personally which is why the different ring technologies appeal to me more. I just wish either Garmin made one or that there was one I didn't have to buy a subscription to use.
People used to sleep with watches 50 years ago too. You just get used to it.
Some plastic silicone straps with the heavier overall weight make it a worse experience that traditional watches

Samsung Galaxy Watch from years ago, still running Tizen. Got it as a company Christmas present, so I'm not too fussed about the mediocre battery life. From what I can tell the Garmin models in the same price range don't last much longer either.
If it makes you feel any better, I've got a perhaps Galaxy Watch 7 from almost a year ago or so running wearOS, and it's battery life is at best at the 36 hour mark regardless. Came from an older tizen-based watch with similar battery life, and at least wearOS is far more funtional.
